Human Escherichia coli O157:H7 Genetic Marker in Isolates of Bovine Origin

The antiterminator Q gene of bacteriophage 933W (Q(933)) was identified upstream of the stx(2) gene in 90% of human disease–origin Escherichia coli O157:H7 isolates and in 44.5% of bovine isolates. Shiga toxin production was higher in Q(933)-positive isolates than Q(933)-negative isolates. This gene...
